ples of which. are illustrated in the accompanying two sheets oidrawings.

Briefly, it may be said to comprise a. casing, a removable framecontained within the casing, two sets of indicating wheels or drums,mechanism for operating the drums, and mechanism for releasing the geartrain and re--Asetting the drums, all so constructed that the parts maybe readily adjustedand so that the mechanism maybe adapted to vehicleshaving dileren't running gear.

Figure l is a front view of mechanism embodying the Fig. 2 is a rearview of the same, the back of the casing beingremoved.- Fig. 3 is a viewoi thefright side of the mechanism frame removed from the casing. Fig. 4is a similar viewof the other side of the frame. Fig. 5 is a verticalsection on theplane oi the line X X of Fig. 2, looking in the directionof theorrows. Fig. (i is a irontview ofthe mechanlrom the casing, withthe drums re leased preparatory to re-se'tting. Fig. 7 isa fragmentarydetail of part oi the mechanism for releasing one set o'i drums. Fig. 8is a detail section plane 0l the line Y Y of Fig. 7.

A is the casing, having openings in the iront for dislplayof theindicating drums.

a a'a are `lugs for attaching the casing to the dashboard or other partoi the vehicle. "a a a/ a are lugs on the inside of the casingforattachment oi the back plate B by means of screws b b.

O D are the side frames for carrying all the operating parts of themechanism. These are Connected together by bracket d and the tubular'rods b b2, and are guided into the casing and held in place therein bythe lugs a. When the back 9i the casing is removed, however, themechanism may be taken out.

E is a journal for attachment oi the transmitting mechanism.

e is a rod attached to th'e end of a flexible shaft e.

The journal E may be attached to the casing in any suitable manner sothat it may be removed when dosited.

F is a worm mounted on the shaitj.

fj are sooketscarried bythe ends of the shaftf, into "mitting rotationto the pinion l:

of the same, on the `this shaft P either one of which the rod e oi mayberemovably secured.

G is a gear carried by the bracket Il and meshing with the Worm F.

g is a bevel pinion rotatable with gear G.

H is a bevel pinion for transmitting rotation to pinion h, bot-h beingmounted on the shaft h, the wheel H being removable. I

the transmitting shaft I is a gear carried by the frame plate D andmeshingno with pinion h;

.T is a gear carried by frame plate D and meshing with gear I and havingpinion j rotatable with it.

K is'a gear wheel meshing with pinion 7' and transat the opposite sideof From this pinion l: the transmitted to two series the frame throughthe shaft k.

L is a gear carried'by the frame plate C meshing vith the pinion k.

M is the shoit The first drum is fast on for the lower series of m. m&c. the shaft, the others being In is a gear rotatablewith shaft M butlongitudinall'y;v

movable thereon, and normally in mesh with the gear L.

'N is s. shaft mounted in the frame, carrying a series 0i star Wheels nn2 dac., for transmitting rotationY one. drum to the other by addition.I Y

The `finit; drum carries numerals' indicating tenths vof a mile, thesecond drum indicates units of miles, dro., to theleft. The last drum m3has a ratchet mi engaged by a spring pawl mi', which prevents it fromrotating backward. l

m is a handle connected by a socket and s'crew thread to the hub of -thepinion m, by which the pinion may be disengaged from the gear L and theentire series of drums rotated for re-setting, if desired. u

O is a gear in mesh with pinion k rotatably mounted on the'screw post o,and normally held in position by the pressure oi the spring of, locatedWithin the hub of the gear and interposed beneath the head ofthe screw.

.P is a shaft for the upper series of drums p p2 dac., the first dmmbeing rotatable with the shaft' and the others being loosely mountedthereon. p is a gear carried by normally in mesh with gearvO.' j I Q isa shaft or rod mounted in the frame carrying a ser-ies of star wheels qq2 circ., which serve to transmit movement from one drum to the next`adjacent one. During the operation of the mechanism, rotation oftheflexible shaft causes rotation of both series 0i drums and l properindication of the distance traveledfbythe numerels on the drums. p

The upper series of drums is intended Ato bereset after each trip, andis therefore adapted to indicate a smaller number of miles than theother series of drums, 1], 0

for instance, 999 9/10.

After a trip the upper series may be readily rea-set.v

R is a countershat carrying gear wheel r, having a removable handle 'rfVwhich when the mechanism is :is-

l S is a lever pivoted to the raine-plate C and having o. cani surface sadapted 'to engage a pin s, which is slidabe iateraly in the.trarne-plate C. s:5 is a spring holding this lever in its normalposition pressing against the snail lc.

i* s a spring Wire serving to trictionally hold the end o the shat Reither in ih position shown in Fie'. 2 or the position shown in Fig. 6.

lt will thus be seen that `ivhile both sets of drums are driven throughthe Worm gear and are consequently normally locked against backwardrotation, either set of drums may be disengaged trom the train andrc-set by its own single handle. The advantagesof such a constructionwill be apparent to those skilled iu the art.

What l claim is:

1. 1n :1 registering mechanism, a series of indicating drums, a train o1gears for rotating the first drum of the series, means i'or transmittingrn'otion between the drums, and a single handle movable longitudinallyfor disconuecting the transmitting gears without affecting said drumsand rotatable for resetting said'drunis.

L. ln :i registering mechanism. a rotatable shatt, a series ofregistering vdrum:Y ounted thereon, Cne of said drums being.,y rotatablewith said shaft, n train of gears for .driving said latter drum, moansfor transmitting motion between the l-rms, n longitudinally movableshifting shaft, means controlled thercbyfor disconnecting one oi thegears of the train, and a geared connection between said shifting shaftand one o said drums.

3. In a registering mechanism, a series ol indicating drums, a train ofgears for driving the first drum of the series, means for transmittingmotion between the drums, a longitudinally movable shait fordisconnecting one of the gears of the train, a multiplying gearconnection between said shaft and the rst drum of said series forresetting, and means ot' connection between sziid shaft and saidlongitudinally movable gc r for simultaneously disengnging said gear andthrowing said multiplying geur into operative position.

,t. ln a registering mechanism, the combination oi iwo series ofindicating drums, a train ol' gears for transmitring motion to said druns, and independently operable means for each of said series of drums fordisconnecting said train and re-settng'said drums.

5. in a registering mechanism, the combination ot' :t trame, e shaftmounted therein. a worm carnied by said shaft, a series otI indicatingdrums, cai-rieti by said frame, a train ot' gears tor transmittingmotion from said Worm to s' id drums, and e. single handle with meansfor c( i nec ng and disconnecting sold drums and said train, forresetting said drums when desired.
